Now a developer called Zach Gerlock has put together Twitch Plays Zelda -- and it's exactly what you'd expect, with hundreds of viewers all playing the original The Legend of Zelda together via Twitch livechat.

Viewers watching a PlayStation 4 or PC broadcast of the game will be able to say specific words into the chat that cause disturbances in the game for the player. Notably, viewers will not be told which words work, and will instead have to discover them for themselves.
